Braking systems test laboratory

Brake discs, brake pads, wheel slide protection, etc.

Our test laboratory uses state-of-the-art, proven measuring equipment to carry out standard measurement tasks but can also offer individual, customised measurement services:

  • Stationary in laboratory
  • Static and dynamic tests (e.g. for accompanying measurements during railway operation field testing)

Accredited test procedures

  • Our test laboratory in Minden is accredited by Deutsche Akkreditierungsstelle GmbH (DAkkS) in the area of brake tests on rail vehicles in accordance with DIN EN ISO/IEC 17025.
  • The accreditation encompasses the relevant test procedures, e.g. in accordance with DIN EN 13979-1, DIN/EN 14535, UIC 541-3, UIC 541-4 and UIC 510-5. See the appendix for the accreditation certificate.
  • DB Systemtechnik is QMS certified to the ISO 9001 standard.

Our tests and test quantities

  • Pad/shoe tests (dry/wet) (coefficients of friction, temperatures, condition of pad/disc before and after, wear)
  • Wheels (coefficients of friction, temperatures, residual stress, deformation (deformation during/after braking), fracture strength)
  • Shaft/wheel brake discs (coefficients of friction, temperatures, wear, fracture strength, power loss due to passive air cooling)
